Jong-Young Park and Su-Hwan Kim

Abstract:Liobargus somjinensis, new species, is described from rivers and tributaries of the western and southern coasts of Korea, and Geogeum Island. The new species can be differentiated from its congeners by the following characters: a broad yellowish, vertical, crescent-shaped band in the middle of the caudal fin; deep black coloration on the outer margin of the dorsal, anal, and caudal fins; a relatively long dorsal spine (7.3-12.4 % SL) and outer mental barbel (15.3-21.6 % SL), and a short distance from dorsal-fin insertion to adipose-fin origin (13.5-22.0 % SL).
